Positive It's great to stay in touch. If you're using it for good things, I think it's really helpful. New places to eat, new places to explore. Negative I feel like it's in control of me.

The jury's out. https://339efcb25eb75e967b0d-ff8eeadd950d51fd1fc939dca75b3973.ssl.cf1.rackcdn.com/assets_default.swf
